spiritual way if we watch them one by one disappear. >> this is sort of a merger between art and science and advocacy in a funny way getting people to wake unand realize what is going on -- wake up and realize what is going on. so it is a memborial trying to get us to interpret history and look to the past. they have always been about lacking at the past so we proceed forward and maybe don't commit the same mistakes. good the transjoint power authority directors meeting for thursday october 11th, our apologies as we are waiting as you know, all of our meetings are recorded by

the staff at sfgov tv and we thank to want them for recording the meetings. roll call. >> and part of taking roll is director sartipi may be delayed in traffic. >> director lloyd? >> here. >> metcalf? >> here. >> reiskin? >> here. >> ortiz? >> present. >> kim? >> here. >> as well, madam chair, you do have a quorum. >> are there any community indications from the board members? seeing none. i will move on to the business. if there is none, so we will move on to the executive director's report. >> great. good morning, directors and members of the public. some good news, i would like to start off by reporting that since our last meeting in september we did donate our wo llie mammoth tooth to the academies of sciences and they are thrilled to receive it and are going to be making it part of the permanent collection and

they will notify us and put together an exhibit to understand what san francisco looked like about 11,000 years ago. we would like to thank the academy for all of their work on our behalf. second i am also pleased to report that our transbay traveling archeology exhibit was awarded the california, preserve vasing foundation, 2012 award. it is quite an honor to receive that award. there were only four awards given for the entire state of california. you had a jury of architecture, engineering and planning and history along with critics from the media, who based the selection on the secretary of interior standards and those have been guiding juries for the past 29 years. and so, later on this month, our own sals, will be traveling down to los angeles to pick up our award. this award as you know is for our archaeological exhibit and it is being shown at ac transit

headquarters and back to san francisco for city hall centennial celebration. on to our work with the san francisco unified school district. as you know we have been working with all of our 28 union and some of our guys are here today. as well as all of our contractors, web core particular, to rereach out to our youth, provide education opportunities, and donation and so forth. and i want to say that web core deserves a great deal of recognition because they have been doing a lot of work in terms of donating the materials to the various schools as well as reaching out to the veteran's community and i would like to have mike pool come up and report to the board on what they have done most recently with tech 21. mike? >> good morning. >> my name is mike pool, i am the senior superintendent on the transpay project. web core and all of us at transbay take pride in giving back to the communities.

in the past few months, we aexisted john o'connell high school tech 21 program by donating the necessary materials and tools to keep this class going. the tech 21 program provides high school students with an opportunity to earn high school credit through hands on construction experience. we hope that our donations allow for the students to have a positive experience and encourage them to pursue construction as a career. we are providing these donations right now. one of the things that they have is they have a beautiful shop, but it is empty. through, the carpenter's union and other contractors we are trying to fill in the shop by making it a working workshop like we had in the old days. lately over the past month, we loaded quite a bit of lumber and start the shop off and build the workbenches and we have to have somewhere to work off to do the projects. so we intend to support this project and even further.

>> thank you for that and thank you web core on your work on our behalf. with respect it our parcels, i want you to know that the city released the rsp for a block nine to develop and design a fully entitled res denial project with ground floor retail that will include housing unit and retail, and neighborhood type serving retail and 580 residential in a 400-foot tower and adjacent 85-foot podium. and the deadline is december 12th, and when that all comes in we will have mike grisle come in and give a presentation to the board. i would like steve to come up and give the bulk of the presentation on our construction update. >> good morning, directors, steve with turner construction, providing construction oversight services. if we could... >> i will do it.

>> it is on here. >> there it is. so, in the past 30 days, great progress has been made on the project. no recordable incidents and no accidents, nothing to report along those lines. another 12 shafts were completed and we were up 140, actually 145 by friday, i believe is the next pour. and closing in on the magic number of 207 early first quarter of next year. they do have a deadline, a milestone of 162 by the end of november. and that is clearly achievable. we have got almost 500,000 craft hours on the project between the utilities and the transit center work. and 60,000 of those were just completed in the last period and the last 30 days. excavation, obviously is continuing across, and the bracing is continuing, the

structure package which is before you on the agenda for later the bids were received during the month of september. and the auxiliary water system continues on mission street and they are working their way down obviously, the unexpected conflicts with other utilities continue as we havene on that but they are working their way through them. the big highlight for this month, they did hit the bottom of the excavation on the end of the project closest to second and howard street. and we are getting started on the micro pile testing and i have pictures of that. coming up in the next period, would be to continue to work on the access trust wound zone three, the micropiles will continue into production in the next 30 to 60 days and one change in plan which does not effect the schedule at all, is the beal street traffic bridge with the operations still in full swing in that zone four area, that eastern area of

project and put off the installation until a three-day weekend in february and they are reporting right now that there is no impact associated with that and does not need to be in place until the excavation is getting down in place and that is not until after the butreses are completed >> over all is on track with the structure being approved and the package being approved today. give them a chance to get geared up to start by the end of the year. that starts with the geothermal package. moving into the structure that is ready for bidding october, november, the last week of october is the current plan. and so that will be the next big piece and so on through the schedule. the bse, which is the major contractor working right now, the beta group continues their work. the only change in this time line is the indication that we are putting off the final traffic bridge until the first

quarter of next year. the over all site view, the trelacs is connected to first street so they can use that to get in and out and they have a ramp in the south east zone where they are continuing the excavation there as well. this the excavation map that we started showing you last period. you can see in the lower left-hand corner that we are down at the very dark pink area, and it indicates are down to what is minus 41, which is practically about 60 feet from the street level and that is the bottom of the excavation and i will show you the pictures here in a second. there is a progress change between the center and western sections. you can see how the tressel bridge is complete with the crane operating off it and connected to first street for access. so, as i mentioned before, we bottomed out. there is the test bed for where the first micropiles will go in and for the pool testing. and here is a shot of those

micropiles going in and they started that two weeks ago and doing the pool test on them this week. if everything passes according to the design, they will be able to start production piles shortly. each final production pile gets tested. there are 1800 of those and this is meant for the whole down of the structure against the pressure of the water. these are not bearing piles. just some more views of the struts and the internal bracing and the excavation in zones one and two continuing. there in zones one and two again. and in zone three, basically the beginning of the month, they were still removing the old wood piles, early in the month, by the middle they were putting up the excess tresle and you can see in the lower right-hand picture and where there they started building the actual access pad, the actual

bridge portion and decking in that lower right-hand corner and now it is in use. zone four, the butress area continues and i know that the picture never changes but we did get 12 more shafts completed and they are on track to meet the next milestone in november. and i wanted to add this production chart and it gives you an idea of how they are meeting their goal. obviously we have got off to a slow start and some of the shafts were deeper in the beginning. and we have now caught up true to their efforts. and we have no problem projecting the 162 by the end of november and of course, the completion by april first of next year. >> 67 left to go of the original 207. this just some shots of their work again. and again, as i said before, awf, the auxiliary water system is continuing down mission street at this time which will be the last long run of that. and they did have a special

event last friday, the folks from web corp and val foreand the subcontractor becker participated in getting about 100 students out from what they call the beaver organization and walked the job for the college-aged kids who are interested in civil engineering and heavy construction. and they were given an opportunity to learn about the project. and hopefully that will keep them interested in the trades and they will move on to be future superintendents and project managers and crafts people. >> the budget remains the same with the packages that have been committed. and we are tracking along those lines. as i said before, most 500,000 man craft hours to date, but we are running with just over 60 percent all local. now, the break-down is there, they are still trending in the same patterns with the 21 percent of the labor force that has reported coming from san

francisco and the area that you know, east, the big contributor. >> and there is the break-down for the last month through the end of september, the entire break-down of where the crafts that are currently working on the project. we have about, we ran some numbers from payroll reports in september, we are run about 215 craft people and that averages between 210 and 215 and that is counting all of the shifts that is the head count typically during the days and i would be happy to answer any questions. >> are there any questions from the board members? >> seeing, none, thank you very much. >> thank you, directors. that concludes my report. >> great. so, at this time we will move on to item number six which is general public comment. are there any of the members of the public that would like to address the board? >> we have not received any indication that a member of the public wanted to address under this item.

>> okay. with that, we can go ahead and move into your regular calendar. >> great. so item number 7. >> item seven is approving an amendment to award a trade subcontract to shimmick construction company. and the responsible bidder submitting lowest response bid in the amount of $111,770,900 for the tg 969 instructeral con street and subinstructer, water proofing... >> directors the report on this item and i should add that the shimmick representatives are also here today. >> good evening, directors, i'm brian dikes the principle engineer. this contract is for below grade the concrete work to fill

up the hole to get back to ground. the cope of work which is fairly lengthy, this microphone is not working, can you hear me right? >> a lot of words here but pictures will come. it makes it easy to understand. basically the bulk of this work consists of almost 100,000 cubic yards of concrete. which is contained in concrete slab, the mat slab at the bottom which is five-foot thick and 200 foot wide and long. and the slab is about, the perimeter walls which are three feet thick and 3500 feet long and almost 50 foot high, this is a really big concrete job. and the duration and anticipated start of concrete work in february, is about 2 years.

>> so, what we did with this contract is we started the work by putting the shoring walls in and this enables us to have a dry bathtub to build concrete in. because the water level is only 12 feet down. and we have an excavation of 60 feet deep. now we have reached the bottom of the excavation where the present contractor is putting down the tie-down piles in and this once that work is finished, is ready to put mat slab, that is the concrete slab which these piles tie down, there is not a big vertical force on this. so it is basically sits on the sand and it is held down against upward water pressure. >> and then the contractor

builds the side, the three-foot thick sidewalls and as they are building, lifts going up it is not fast work, because you have got to move the bracing and the shoring that you saw in the previous pictures and rebrace it each time as you go up. he builds the columns that support the mezzaninelevel. >> and next it puts in the steel beams of what is put in on the contractor and the thing progresses. and so that is the next big contract, which is likely the biggest single contract of the structure which gets us all the way up to the roof. in addition to all of the steel and concrete, there are some fairly substantial specialty subcontractor work. two items, which are being handed over to shimmick to manage but not part of the bid.

they were previously bid an award. of the geothermal loop in the work which has to go in before the concrete mat slab goes down because it is heat exchange tubes are below. there are some specialized and subcontract works. there is is a water proofing system so this whole, like any underground concrete work you don't want leaks and stains like you do see in some of the stations in the middle of town. which was a long time ago. there are small contracts for the county collector plumbing and communications not to do the actual work but to put in the conduits and the collections for it. but there is part of the main part of the work is the large subcontract for rebar. the procurement process that we issued the request for calls in

november of last year. sorry. and we got 6 packages. the panel has evaluated qualified five, and one contractor was excluded he could not come up with even half of the bonding available to do the project this big. so we sent out the invitation for bid in may. and there were during the bid period, which added some additional items to the contract this work. and around about $3 million worth of extra work, better to get a bid now than to do it by change order. the engineers estimate was 95 million, including all of the allowance item for the police force for traffic control. we received three bids, two

bidders dropped out. mainly they were panko and key wood pacific, both of whom gave the same reason, they had acquired too many other jobs in the interum period especially panko, but the jobs started and you can see the buildings going up in the city. the lowest bid was received from shimmick construction company and that is the one that i am recommending. we have no bid protests from the other bidders. so, we are recommended to go ahead with an award to shimmick. not only are they qualified, but they are a large contractor who handle large work in california, not just all over the whole country. some examples being in a joint venture they did the mta side in los angeles, a $600 million, contract and the joint venture partners some year ago was

obayashi so there is a working relationship there. >> they did the golden gate bridge, and the south approving $58 million. and the waste water treatment plant, all concrete, $50 million themself and not subcontracted. they did a large dam, and southern california for $94 million, all concrete work, slip ways. and just recently, the warm springs extension $137 million. they are what i would call the 97 percent level, which is the reason that we got them to the bidder they need to move on to the next job with a crew and they are bringing subcontractors. and they have by experience, they have 18 percent sbe participation which is slightly exceeded our goal. the largest of those sbe contracts is actually $15 million out of the $20 million which is the land of oso

brothers and hey wood, they are a very good concrete finisher and i worked with them on other jobs and in other people's bids too. the largest single subcontractor is not sbe, that is rebar contract, which is $32.6 million. there is a lot of steel to get into this job. it is not a company that i know, it is in fact a holding company that bought up pacific coast steel, so we are really getting pacific coast steel. but they are no longer sbe because they are bought out by a multinational which happens. this is the lowest responsive bid. it is a balanced bid from my experience, the contractor is not loaded. and so i am very comfortable to recommend it and i would look forward to working with shimmick as the kind of people that are going in price and their coming out prices are very much the same number, a small percentage increase

usually change orders not claims. >> any questions? >> i do have one, director ortiz? >> i am trying to understand all of this increases and all of that stuff. when you saying there by increasing authorized direct costs by $110 million. is that to web core original work? what is? it is increased to what? >> well, web core on this project is general contractor. and we get permission to them to award contracts, that we take out to bid and the $111.7 million is shimmick's bid to do the work that is the work that covers all of it. the markup that you see, the extra $9 million is in fact the percentage in our contract with web core for them to administer to make concern that there were no glitches between the contractors that were working on the job and the general contractor responsible. >> so when you say, therefore

increasing authorized direct costs by $111... what are they increasing? >> web core's contract is increased each time that we let in a new subject. we did not give them a contract for the $580, 600 million off the start of the project. we give them a contract that goes up every time that the board approves, another package for construction. >> okay. >> we were expecting to do this below grade package work and all of that? >> oh, yes. >> absolutely. >> the next package in that $500,80 million plus. >> i couple of questions. i realize this is a structural, but is there any recycled content specified in the concrete? >> this is construction, it is not a recycle clause and we

have that in the excavation, demolition and removal. >> we are not taking anything out. >> i am talking about the specification for the concrete that you are putting in. >> there is specified what we call free ash which is a recycled material, yes. but you have to be careful how much you... you put in too much it is difficult to get a decent set on the concrete. yes, there is not in the rebar. it is not recycled from overseas. >> okay. >> i would not recommend that. >> right. >> the two subcontracts that you are going to bring in under shimmick, was it the intent all along to do that? the geothermal and the electrical? >> yes, those contracts have already been awarded to web core. at web core and to shimmick and

so shimmick can manage their work along with the small subcontract. >> if that was the intent is there a reason why they were done in advance separately. >> yes, the geothermal and grounding work will actually be starting in the next few, in the next month or so. >> okay. >> they had to get all of their shop drawings submitals and everything in and approved without delay. so, we did it that way rather than having a period when there might be no work happening. as soon as we get to the bottom and we get the micropiles in, we want to start work. to get the bottom mapped in as soon as possible. you don't want an excavation this depth left open for six months or so. >> that makes sense. >> and finally, with regard to the bids, the report was, did a very good job of explaining why they came in higher, than expect and what is happening

with the market for some of the commodities that are involved here. two questions, related. what do you think accounts for the large range and the three bids that you got? and then second, does the trend that we are seeing, with this package, any cause for concern or are we thinking about the super structure package and beyond in terms of the budget or us estimates that we currently have. >> i will take the first part trying not to confuse. >> the first part, we had three bids, the actual range and you say large, the high bid was contractor on-site who made a bid. out of the questions that we got out of the bidding period, if there were 500 questions, he asked 490 of them. i think that he was trying to fight off the other contract but it didn't work.

i am being as frank as i can in a public meeting. i was disappointed with that bid after all the contractor on site should have been competitive. the other bid in the middle was very competitive. except they made a mistake. he actually cut his bid $10 million in the last minute but wrote in the wrong numbers. the addition came to $11 million, and he was actually only $1 million above. but people who do these 24th last hour bids can make mistakes over the phone. and the number one, 11 is the correct addition if you took the number that he wrote in it was just a million dollars over. it was very competitive and if i had to recommend the other contract. >> and i have got the best bid at the best price. >> okay. >> in terms of the feature of

the projects the costs of escalating. >> the next bid to come out, there is a series to come out. but the next big one is the structural steel contract it has very little concrete in it. there are some concrete on the steel deckings. it is not large quantities that will stretch the market here at all. there is very little rebar in that. such that we have... i think that it is six, qualified bidders, and one of them said that he is dropping out because the others are too well established on the west coast and he came from the east coast. but we still got five very good bidders and they are keen on it. the work it has... it is not... it is a different material. most of the buildings or not all of them, maybe all of the buildings that we are see there are reinforce
